The Rand and Inez veins are located in a mountain valley 20 kilometres northwest of Salmo. These are part of the Second Relief mine (082FSW187) which was the third largest gold-enriched skarn producer in the province.

The area is underlain by lapilli tuff and augite porphyry volcanics of the Elise Formation and siltstone, sandstone, argillite and quartzite of the Archibald Formation, both of the Lower Jurassic Rossland Group. These occur as a roof pendant within granodiorite of the Bonnington pluton of the Middle to Late Jurassic Nelson Intrusions. The veins occur on the west limb of a small anticline, whose axis runs down the Erie Creek valley, near the Red Mountain fault.

The Rand and Inez vein systems crosscut the sediment-volcanic stratigraphy, striking generally northeast with steep northwest dips, converging towards the No. 2 adit. Vein mineralization is generally erratic comprising mineralized lenses of massive sulphides in the order of 0.4 by 9 metres along strike. Mineralization consists of pyrite, pyrrhotite and chalcopyrite. Gold also occurs as very fine flakes and minute particles.

The Inez vein structure, located west of Erie Creek, extends 320 metres from northeast to southwest. On this structure, 7 zones of possible significant mineralization have been identified. At the portal, the Inez vein is on the hanging wall of a banded, light buff coloured, 1-metre thick rhyolite dyke which is strongly faulted at the footwall contact. The vein is hosted in fragmental volcanic rocks with bands of siliceous hornfelsed sedimentary rocks. Sampling of these seven zones across intervals up to 2.37 metres in width and lengths of up to 35 metres assayed up to 21.73 grams per tonne gold (Vancouver Stockwatch, Sept. 12, 1989).

The Rand vein has been traced on surface for over 420 metres. The vein is cut off at the No. 2 portal crosscut by a strong fault containing up to 12 centimetres of gouge of crushed wallrock. A grab sample of weathered material, from the Rand vein, containing pyrrhotite and quartz assayed 238.9 grams per tonne gold and 38.05 grams per tonne silver (Vancouver Stockwatch, July 11, 1989). An unknown amount of ore was extracted from this vein.
